Tracing heavy metals in ‘swine manure - maggot - chicken’ production chain.

With the development of large-scale livestock farming, manure pollution has drawn much attention

Abstract

With the development of large-scale livestock farming, manure pollution has drawn much attention. Conversion by insects is a rapid and cost-effective new method for manure management. Swine manure conversion with maggots has developed, and the harvested maggots are often used as animal feed. However, the flow of heavy metals from manure to downstream processes cannot be ignored, and therefore, heavy metal content was measured in untreated raw manure, maggottreated manure, harvested maggots and maggot-eating chickens (chest muscle and liver) to evaluate potential heavy metal risks.
